The "Invalid Token" is almost always because you have cookies disabled, or multiple cookies stored on your browser.
If you have a cookie stored for solarchat.natca.net and you use solarchat.solarastronomy.org to log in, or visa-versa you will get the invalid token error. This can be fixed by deleting your cookie for the site.

If you have cookies disabled on your browser in the security settings , you will get the invalid cookie error. If you have a corrupt cookie stored in your browser, you will get the invalid token error. There are several different versions of each browser so I can't list the exact ways to fix this in every browser. If you silly go to your google search page and type "how do I enable cookies in [browser and version]" or "how do I delete cookies in [browser and version]" you will get the fix.

Now, the slow internet speed issue seemed to be only with Asimov and George, both in Australia or nearby. If you experience slow speeds the first thing you should do is go immediately to www.speedtest.net and test your internet speed. John and I did this on the Facebook CBSAP page and found that his current upload speed was just over 1Mbps. This means that he can upload a megabyte of data in 8 seconds under ideal, steady conditions. a megabit is 1/8 of a megabyte. Normally with an upload speed of 1Mbps it takes about 10-15 seconds to upload a 1MB file with error correction and verification. His download speed was around 6Mbps which means it will probably take 3-4 seconds to view the image in his post.
My up speed in Atlanta is 22Mbps which means that I can upload 1Megabyte of data in about .6 seconds. My download speed is 120Mbps so I can view the 1MB file instantaneously. The NATCA server itself is blazingly fast and there isn't an internet server on Earth that can download it faster than it can send, or upload it faster than it can receive it it so this isn't usually the problem.
Of course, sometimes there are sever issues but they would be characterized by widespread slow downs to all users.
